Integrated DLT and non-DLT system design for central bank digital currency

Central Bank Digital Currency (CBDC) is gaining popularity due to its potential benefit. However, experiments to explore the Distributed Ledger Technology (DLT) based CBDC is mostly done in the wholesale area, not in the retail area which has more impact on the public. This paper proposes a CBDC design where the digital currency or token that is distributed in the wholesale DLT network, can be widely accessed by the public through accounts provided by commercial banks. The proposed design maintains reliability as well as user-friendliness and scalability. This paper describes the architecture, infrastructure, and business process of the proposed design.
